Canadian Copper Mountain Mining (CMMC) shut down their mill after a December 27th ransomware attack “as a preventative measure to determine the status of its control system, while other processes switched to manual operations”. Off-line process sensor monitoring of the physics system would not be susceptible as neither IT malware nor ransomware could reach the sensor monitoring or the process. This means that the mill may NOT have needed to be shut down if the process sensors indicated the process was not affected. As any IP network can be hacked, monitoring the physics of the sensors off-line is arguably the only approach to justify continued operation during a ransomware or other IT cyberattack. As some in the insurance industry are stating that they will not insure ransomware, one wonders how the insurance industry will view manual shutdowns that could have been prevented by the monitoring of the process sensor physics.

Ecellent points. But this could be hard to do quickly in the middle of the night or on a Holiday Week End. There would be ricks but it really seems worth the effort if they have a plan in place ahead of time. More firewalls and monitoring for hackers would also be part of this plan.
